CLIMATE  OF  ILLINOIS 

BY  J.  G.  MOSIEK,  CHIEF  IN  SOIL  PHYSICS 

Illinois  is  so  situated  that  its  northern  boundary  is  21/4  degrees 
south  of  the  center  of  the  north  temperate  zone,  while  its  southern 
extremity  is  only  13y2  degrees  from  the  torrid  zone.  It  extends  over 
51/2  degrees  of  latitude,  with  a  difference  of  about  2  degrees  in  mean 
temperature  for  each  degree  in  latitude.  The  altitude  varies  from 
310  feet  in  the  extreme  southern  part  of  the  state  to  1,257  feet  in  Jo 
Daviess  county,  the  highest  point  in  the  state.  The  Ozark  Uidge,  ex- 
tending east  and  west  across  the  state  near  the  southern  end,  reaches 
an  altitude  of  1,046  feet  in  the  northwestern  part  of  Pope  county. 
About  70  percent  of  tb^  state  lies  between  500  and  700  feet  above  sea 
level. 

The  state  is  entirely  within  the  belt  of  prevailing  westerly  winds 
with  their  accompanying  cyclones,  or '"lows,"  and  anticyclones,  or 
"highs."  To  these  "lows"  and  "highs,"  as  they  are  commonly 
designated  by  the  forecaster  and  on  the  weather  map,  is  due  the  ordi- 
nary weather  of  the  state.  As  our  weather  changes  are  almost  entirely 
due  to  the  passage  of  cyclonic  storms  across  the  country,  their  impor- 
tance requires  some  notice  here. 

WEATHER  CHANGES  PRODUCED  BY  CYCLONES,  OR  Lows,  AND  ANTI- 
CYCLONES, OR  HIGHS 

A  cyclone,  or  low,  is  a  storm  having  an  atmospheric  pressure  lower 
than  the  normal  due  to  the  rising  of  the  air  in  the  sto  -in  area.  Since  a 
cyclone  is  a  whirling  storm,  or  whirlwind,  the  wind  does  not  blow 
directly  in  toward  the  center  of  the  low,  but  somewhat  spirally  and 
counter-clockwise.  As  the  low  passes  eastward,  the  wind  changes  to 
the  northwest,  either  thru  the  southwest  or  the  northeast,  depending 
upon  the  part  of  the  low  passing  over  the  locality.  If  the  center  of 
the  low  is  to  the  north,  then  the  wind  shifts  to  the  south,  the  south- 
west, and  finally  to  the  northwest.  If  the  center  of  the  low  is  to  the 
south,  the  wind  shifts  to  the  nortlrwest  thru  the  northeast  and  north. 
In  either  case,  when  the  wind  becomes  northwesterly  the  temperature 
becomes  lower.  "When  the  center  of  the  low  passes  over  a  locality,  there 
is  usually  a  sudden  change  of  the  wind  to  a  westerly  or  northwesterly 
direction,  with  an  accompanying  change  in  temperature.  Clearing 
weather  usually  follows  the  passage  of  the  center,  and  the  rear  of 
the  low  is  marked  by  cooler,  clear  weather.

By  knowing  the  direction  and  the  rate  of  movement  of  these 
cyclones,  one  may  plan  his  work  so  as  to  avoid  being  taken  unawares' 
by  many  of  these  storms.  The  daily  weather  map  or  even  the  daily 
paper  will  give  valuable  information  in  regard  to  their  movement. 
If  rain  is  predicted  within  twenty-four  hours  for  Kansas,  Nebraska, 
Missouri,  or  Iowa,  the  chances  are  that  within  thirty-six  hours  the 
0same  condition  will  prevail  in  Illinois. 

DISTRICTS  OF  THE  STATE 

For  convenience  the  state  has  been  divided  into  five  districts  as 
follows : 

(1)  Extreme  northern  district,  including  the  tier  of  counties 
along  the  Wisconsin  line. 

(2)  Central-northern  district,  including  the  counties  between 
the  extreme  northern  division  and  an  irregular  line  extending  across 
the  state  on  the  southern  lines  of  Henderson,  Warren,  Knox,  Peoria, 
Woodford,  Livingston,  and  Iroquois  counties  (crossing  Ford). 

(3)  Central  district,  including  the  counties  between  the  south- 
ern boundary  of  the  central-northern  district  and  a  line  on  the  south 
boundary  of  Jersey,  Macoupin,  Montgomery,   Shelby,   Cumberland, 
and  Clark  counties. 

(4)  Central-southern  district,  including  the  counties  south  of 
the  central  district  and  north  of  the  Ozark  Ridge. 

(5)  Extreme  southern  district,  including  the  seven  most  south- 
ern counties. 

The  extreme  northern  district  includes  counties  that  are  on  the 
border  of  the  corn  belt.  The  central-northern  and  the  central  divi- 
sions include  the  corn  belt  proper,  while  the  central-southern  includes 
practically  all  that  portion  of  the  state  in  the  lower  Illinoisan  glaci- 
ation.  (See  general  soil  map  of  Illinois  in  Bulletin  193).  The  seven 
southern  counties  are  unglaciated  and  form  a  distinct  soil  and  physi- 
ographic region  by  themselves.

RAINFALL 

The  primary  cause  for  precipitation  is  the  condensation  of 
vapor  in  the  atmosphere  as  a  result  of  the  lowering  of  the  temper- 
ature. This  change  in  temperature  may  be  brought  about  by  a  current 
of  moist  air  rising  to  a  higher  altitude,  by  a  warm  vapor-laden  air  cur- 
rent meeting  a  cold  one,  or  by  movement  of  the  air  from  warmer  to 
cooler  regions,  as  from  tropical  to  temperate  regions.  The  amount  of* 
precipitation  depends  upon  the  extent  of  the  cooling  and  the  amount  of 
vapor  carried  in  the  air.  In  general,  the  amount  of  precipitation 
diminishes  as  distance  from  the  equator  increases.  Many  local 
variations  occur,  however,  that  are  due  to  differences  of  altitude, 
direction  of  wind,  etc.  These  variations  may  produce  extremely 
heavy  rainfall  over  small  areas  and  at  certain  seasons. 

The  distribution  of  the  rainfall  by  months  varies  with  the  dif- 
ferent sections  of  the  state,  as  shown  by  the  diagram  on  page  21.  In 
the  extreme  northern  and  central-northern  districts  the  six  months 
April  to  September  form  the  period  of  greatest  rainfall,  while  in  the 
extreme  southern  district  the  precipitation  is  more  evenly  distrib- 
uted, with  August,  September,  and  October  as  the  driest  months. 

RELATION  or  RAINFALL  TO  CROPS 

Two.  factors  of  climate  are  of  special  importance  in  the  growth 
of  crops.  These  are  precipitation  and  temperature.  The  supply  of 
moisture  for  the  soil  and  the  crop  is  derived  entirely  from  precipita- 
tion either  as  snow  or  as  rain.  No  large  excess  is  needed,  and  we 
are  frequently  surprised  at  the  size  of  «rops  that  may  be  grown  with 
a  small,  well-distributed  rainfall.  From  300  to  500  pounds  of  water 
are  required  by  the  plant  in  order  that  it  may  produce  one  pound  of 
dry  matter.  A  100-bushel  crop  of  corn  requires  for  its  production 
about  16  inches  of  water,  or  about  18  tons  for  each  bushel  of  shelled 
corn  weighing  56  pounds.  A  100-bushel  crop  of  oats  requires  18 
inches,  or  20  tons  for  a  bushel  of  grain,  and  a  ton  of  Clover  hay  re- 
quires about  450  tons  of  water. 

There  is  sufficient  rainfall  almost  every. year  to  produce  max- 
imum crops.  The  difficulty  is  with  its  -distribution.  The  average 
yearly  rainfall  for  the  state  is  37.98  inches,  or  more  than  3  inches 
per  month,  but  during  the  ten  years  from  1906  to  1915  at  the  Uni- 
versity of  Illinois  there  have  been  twenty-five  periods  of  20  days  or 
longer  in  which  the  rainfall  has  been  less  than  one  inch.  Of  these 
dry  periods,  six  have  been  30  days  or  more  in  length.  The  injury 
resulting  from  the  irregularity  in  the  distribution  of  the  rainfall 
may  be  prevented  to  some  extent  by  drainage,  tillage,  increasing 
and  maintaining  the  organic  matter  of  soils,  and  keeping  the  soils 
well  supplied  with  plant  food. 


1918.]  CLIMATE  OF  ILLINOIS  11 

This  uneven  distribution  of  the  rainfall  is  a  sufficient  incentive 
to  cause  the  farmer  to  take  every  precaution  for  storing  and  holding 
the  moisture  in  the  soil  before  the  crop  is  planted  by  preparing  a 
deep,  mellow  seed  bed,  or  for  carrying  off  quickly  excessive  amounts  of 
rain.  Corn  should  receive  an  average  of  at  least  2.5  inches  of  rain- 
fall per  month  during  the  three  months  of  its  growth.  The  effects 
of  rainfall  during  June,  July,  and  August  upon  corn  yields  are 
shown  by  the  records  of  the  old  continuous  corn  plot  at  the  Uni- 
versity. Corn  has  been  grown  on  this  plot  since  1879,  but  there  is 
no  record  of  the  yields  previous  to  1889. 

Summer  rainfall 

— Less  than  7  inches 25.3  bu.  per  acre  (8-year  av.) 

— Between  7  and  10  inches 32.4  bu.  per  acre  (9-year  av.) 

— Over  10  inches 39.8  bu.  per  acre  (11-year  av.) 

When  the  rainfall  was  less  than  two  inches  per  month,  the  yield 
was  reduced,  for  a  four-year  average,  to  24.4  bushels  per  acre,  and 
when  the  rainfall  was  over  thirteen  inches,  the  yield  was  45.9  bushels 
per  acre,  for  a  seven-year  average.  This  is  a  difference  of  21.5  bush- 
ek  between  yields  produced  with  what  might  be  called  the  maximum 
rainfall  and  those  produced  with  the  minimum,  at  the  University  of 
Illinois.  It  is  evident  from  this  that  a  month  during  which  there 
is  less  than  two  inches  of-  rainfall  may  be  regarded  as  a  dry  month.

EXTREME  NORTHERN  DISTRICT 

The  average  annual  precipitation  for  the  extreme  northern  district 
is  33.99  inches,  as  shown  by  the  records  for  the  fifty  years  from  1866  to 
1915.  This  is  9.29  inches  less  than  the  average  for  the  extreme  southern 
district.  However,  the  rainfall  in  this  district  is  better  distributed 
for  the  growing  of  crops  than  is  that  in  any  other  part  of  the  state — 
a  fact  which  about  compensates  for  the  smaller  total.  From  March 
to  August  the  average  rainfall  is  20.56  inches,  or  60.4  percent  of  the 
average  annual  rainfall.  During  the  winter  the  average  rainfall 
is  5.44  inches;  during  spring,  9.34  inches,  during  summer,  11.22 
inches ;  and  during  fall,  7.99  inches. 

June  is  the  month  of  greatest  rainfall,  while  May  has  an  aver- 
age of  only  .07  inch  less.  During  the  last  twenty  years,  however, 
May  has  had  an  average  of  over  one  inch  more  than  June.  Febru- 
ary and  December  have  the  le#st  precipitation.  The  highest  aver- 
age monthly  rainfall  for  any  ten-year  period  was  5.03  inches  for 
June,  1876-1885,  while  July  of  the  same  period  follows  with  4.88 
inches,  and  May,  1906-1915,  with  4.63  inches,  is  next. 

The  lowest  average  monthly  precipitation  for  a  ten-year  period 
was  1.34  inches  for  December,  1896-1905.  The  lowest  rainfall  re- 
corded for  any  month  during  the  growing  season  was  .10  inch  at 
Winnebago,  for  August,  1889,  while  the  heaviest  was  15.73  inches 
at  Riley,  for  September,  1894.

1918}  CLIMATE  OF  ILLINOIS  13 

About  two  out  of  every  five  Marches  are  relatively  dry,  having 
less  than  two  inches  of  rain,  while  one  April  in  every  four  is  dry. 
May  once  in  eight  years  is  dry,  June  twice  in  thirteen  years,  July 
once  in  five  years,  and  August  twice  in  eight  years.  The  greatest 
range  in  the  average  annual  rainfall  during  the  fifty  years  has  been 
27.11  inches— from  22.20  inches  in  1901  to  49.31  inches  in  1892. 

CENTRAL-NORTHERN  DISTRICT 

For  the  central-northern  district  the  records  of  the  sixty  years 
from  1856  to  1915  show  an  average  annual  rainfall  of  34.26  inches. 
This  is  only  .27  inch  more  than  the  rainfall  for  the  extreme  northern 
district.  From  March  to  August  the  central-northern  district  receives 
20.35  inches,  or  59.4  percent  of  its  rainfall.  The  average  precipita- 
tion in  winter  is  5.80  inches ;  in  spring,  9.60  inches ;  in  summer,  10.75 
inches;  and  in  fall,  8.11  inches.  The  lowest  annual  rainfall  recorded 
was  23.17  inches  in  1901,  and  the  highest  49.25  inches  in  1902. 

May  is  the  month  of  greatest  rainfall,  with  an  average  of  4.05 
inches,  and  June  is  next,  with  3.74  inches.  The  highest  average 
rainfall  for  a  period  of  ten  years  occurred  in  June  from  1876  to  1885, 
the  average  being  5.11  inches.  May  follows  with  4.48  inches  as  an 
average  of  the  years  1906  to  1915. 

January  is  the  month  of  lowest  rainfall,  the  average  for  the 
sixty  years  being  1.88  inches.  Among  the  ten-year  averages,  the 
month  of  December  during  the  years  1896  to  1905  is  the  lowest,  with 
1.34  inches,  while  February  is  next  with  1.44  inches  as  an  average  of 
the  years  1866  to  1875. 

The  recurrence  of  dry  periods  is  about  the  same  as  in  the  extreme 
northern  district.  One-third  of  the  Marches  are.  dry,  having  less  than 
two  inches  of  rainfall ;  also  one-fourth  of  the  Aprils,  one-tenth  of  the 
Mays,  one-ninth  of  the  Junes,  two-elevenths  of  the  Julys,  and  two- 
ninths  of  the  Augusts.  The  lowest  rainfall  recorded  at  any  of  the 
twenty-three  stations  of  this  district  during  the  growing  season  was 
.10  inch  at  Aledo  in  July,  1913,  and  the  same  amount  at  Lanark  in 
April,  1915.  The  heaviest  rainfall  for  any  month  was  20.03  inches

highest  ten-year  average  was  40.54  inches  for  the  years  1876  to  1885, 
while  the  lowest  was  34.11  inches  for  the  years  1886  to  1895 — a  differ- 
ence of  6.43  inches.  From  March  to  August  the  average  precipitation

during  the  fall,  8.GO  inches.  The  lowest  precipitation  for  any  one 
year  was  24.12  inches  in  1879.  In  1901  the  total  rainfall  was  26.43 
inches;  and  in  1914,  25.83  inches.  The  greatest  annual  rainfall  was 
48.24  inches  in  1876. 

June  is  the  month  of  highest  average  rainfall,  with  4.11  inches. 
May  and  July  follow  closely  with  4.04  and  3.89  inches.  The  highest 
average  monthly  rainfall  for  a  ten-year  period  was  5.50  inches  for

ten-year  period,  the  average  for  the  years  1886  to  1895  having  been 
only  1.50  inches. 

The  recurrence  of  months  with  less  than  two  inches  of  rainfall 
is  less  frequent  in  this  district  than  in  the  central  district  and  other 
districts  farther  to  the  north.  The  greater  injurious  effects  from 
drouth  are  due  almost  entirely  to  soil  conditions.  Time  will  be  re- 
quired to  remedy  these.  Heavy  applications  of  limestone  must  be 
made,  deep-rooting  crops  must  be  grown  to  loosen  the  subsoil,  and  or- 
ganic matter  of  every  available  kind  must  be  incorporated  with  the 
soil.  This  will  put  the  soil  in  better  condition  to  absorb  and  retain 
moisture. 

As  an  average,  two  Marches  in  every  fifteen  years  are  dry,  two 
Aprils  in  every  nine  years,  one  May  in  every  twelve  years,  one  June  in 
every  twelve  years,  one  July  in  every  ten  years,  and  one  August  in 
every  five  years. 

The  lightest  rainfall  recorded  in  this  district,  for  any  one  month 
during  the  growing  season,  was  a  trace  in  April,  1915,  at  Fairfield, 
and  the  same  in  August,  1909,  at  Carlyle.  The  greatest  rainfall  was 
15.30  inches  in  July,  1875,  at  Flora.  The  heaviest  monthly  rainfall 
recorded  at  St.  Louis,  Missouri,  was  17.07  inches  in  June,  1848. 

EXTREME  SOUTHERN  DISTRICT 

The  extreme  southern  district  includes  the  Ozark  Ridge  region 
and  some  extensive  bottom  lands.  Records  for  the  fifty  years  from 
1866  to  1915  show  the  average  annual  rainfall  to  be  43.28  inches,  which 
is  9.29  inches  more  than  that  of  the  extreme  northern  district  for  the 
same  period.  From  March  to  August  the  average  rainfall  is  23.08 
inches,  or  53.3  percent  of  the  average  annual  rainfall.  During  the 
winter  months  it  is  10.66  inches ;  during  the  spring,  12.38  inches ; 
during  summer,  10.70  inches ;  and  during  fall,  9.54  inches.  The  lowest 
annual  rainfall  was  26.52  inches  in  1872,  while  the  greatest  was  62.89 
inches  in  1882. 

March  is  the  month  of  greatest  rainfall,  having  an  average  for 
fifty  years  of  4.38  inches.  June  is  next  with  4.05  inches.  The  high- 
est average  monthly  rainfall  for  a  ten-year  period  was  5.53  inches 
for  June  in  the  years  1876  to  1885. 

October  is  the  month  of  lowest  rainfall,  with  an  average  of  only 
2.80  inches.  The  lowest  average  monthly  rainfall  for  a  ten-year  pe- 
riod was  1.90  inches  for  October  during  the  years  1886  to  1895. 
From  1866  to  1875  an  average  of  only  1.91  inches  of  rain  fell  during 
October. 

Months  of  low  rainfall  are  no  more  common  in  this  district  than 
in  the  northern  districts.  One  in  every  seven  Marches  is  dry,  or  has 
less  than  two  inches  of  rain,  one  in  ten  Aprils,  two  in  eleven  Mays,

part,  and  also  the  almost  uniform  summer  precipitation  thruout  the 
state.  The  spring  rainfall  shows  a  very  distinct  increase  southward ; 
the  autumn  rainfall  also  increases  southward  but  to  a  less  degree.  ( The 
more  severe  effects  of  drouth  in  southern  Illinois  are  very  largely  due 
to  the  character  of  the  soil.  The  average  temperature  for  July  and 
August  is  only  1.7  degrees  higher  for  the  central-southern  than  for 
the  central  district,  altho  for  January  and  February  it  is  4.3  degrees 
higher.) 

SNOWFALL 

The  winter  precipitation  in  the  form  of  snow  plays  a  very  impor- 
tant part  in  crop  production.  The  water  from  the  melting  snow 
sinks  into  the  soil,  if  it  is  not  frozen,  with  less  run-off  than  there  is 
with  the  same  amount  of  rainfall.  If  the  soil  is  frozen  and  the  melt- 
ing is  rapid,  much  run-off  occurs  and  is  frequently  accompanied  by 
floods. 

However,  the  greatest  value  of  snow  in  humid  regions  is  not  the 
moisture  it  supplies  to  the  soil,  but  the  protection  it  affords  the  crops 
that  live  in  the  soil  overwinter,  such  as  alfalfa,  clover,  and  wheat.  Snow 
prevents  the  alternate  freezing  and  thawing  which  results  in  injury  to 
the  crops.  Open  Avinters  are  very  damaging,  especially  where  the  soil  is 
not  well  drained.  When  freezing  occurs,  the  soil  is  frozen  fast  to  the 
roots;  when  upward  expansion  takes  place,  the  plant  is  raised;  and 
when  thawing  occurs,  the  soil  settles  back  but  the  plant  does  not.  Re- 
peated freezings  cause  the  plant  to  be  heaved  from  the  soil.  If  the  soil 
is  well  drained,  the  expansion  of  freezing  will  be  taken  care  of  largely

within  the  pore  space  of  the  soil  itself,  or  the  soil  may  not  grip  the 
plant  with  sufficient  firmness  to  loosen  the  deeper  roots. 

Snow,  being  a  poor  conductor  of  heat,  forms  a  very  effective  cov- 
ering for  the  winter  crops.  During  periods  of  intense  cold  the  tem- 
perature of  the  soil  one  inch  deep  beneath  the  snow  is  much  higher 
than  the  temperature  of  the  air  above.  Experiments  show  that  the 
temperature  on  top  of  a  snow  is  from  11  to  15  degrees  lower  than  the 
ground  under  a  4-inch  snow. 

The  average  annual  snowfall  for  the  central-southern  and  ex- 
treme southern  districts  is  17.5  inches;  for  the  central,  23.3  inches; 
and  for  the  central-northern  and  extreme  northern,  31.7  inches.  The 
average  for  the  st^te  is  24.7  inches. 

One  of  the  most  important  factors  in  the  protection  which  the 
snow  offers  to  a  crop  is  its  duration  on  the  land.  In  the  northern 
quarter  of  the  state,  snow  remains  on  the  ground  during  a  large  part 
of  the  winter,  while  in  the  central  and  southern  districts  it  is  the  ex- 
ception for  it  to  remain  more  than  a  week.

TEMPERATURE 

RELATION  OF  TEMPERATURE  TO  GROWTH  OF  CROPS 

From  the  extreme  northern  to  the  extreme  southern  boundaries 
of  Illinois  there  are  eleven  degrees  of  difference  in  mean  temperature 
and  four  and  one-half  weeks  difference  in  the  length  of  the  growing 
season.  These  differences  produce  a  marked  effect  upon  the  character 
and  the  kinds  of  crops  that  are  commonly  grown  in  the  state.  Cotton 
may  be  produced  in  the  extreme  southern  part,  where  the  climate  is 
moderated  by  the  latitude  and  possibly  also  in  some  small  degree  by 
the  pouring  of  floods  of  the  warm  waters  from  the  Cumberland  and 
Tennessee  rivers  into  the  Ohio  river.  In  the  north  end  of  the  state 
early-maturing  varieties  of  corn  must  be  planted,  and  even  these  are 
sometimes  badly  damaged  by  early  frosts.  The  high  temperatures  in 
the  south  third  of  the  state  commonly  prevent  the  successful  growing 
of  oats  there,  while  in  the  extreme  north  oats  are  one  of  the  most  suc- 
cessful crops.  The  native  vegetation,  and  especially  the  forest  trees 
of  the  extreme  sections,  show  very  striking  differences.  The  beech, 
the  tulip,  the  gums,  the  post  oak,  and  the  water  oak,  for  instance,  are 
confined  to  the  southern  part  of  the  state. 

The  first  vital  function  of  plants  which  is  greatly  influenced  by 
temperature  is  that  of  germination.  Seeds  do  not  germinate  well  if 
the  soil  is  too  cold.  Oats,  wheat,  rye,  flax,  and  clover  will  germinate 
slowly  at  temperatures  between  32°  and  40°  F.,  tho  much  higher  tem- 
peratures are  best.  Corn  requires  a  high  temperature  for  quick  ger- 
mination. In  a  test  by  Haberlandt,  eleven  days  at  51°  F.  were  re- 
quired for  the  sprout  to  show,  while  at  65°  only  three  days  were  nec- 
essary. Germination  should  be  as  rapid  as  possible  in  order  to  lessen 
the  danger  from  decay  and  the  likelihood  of  attacks  of  fungi  which 
•destroy  the  seed.

the  common,  and  undoubtedly  true,  impression  of  farmers  is  that 
wheat  makes  some  growth  even  under  snow.  Corn  makes  practically 
no  growth  below  49°  F.  For  normal  rapid  growth  the  temperature 
of  the  soil  must  be  75°  or  above,  at  least  during  part  of  the  day.  Al- 
falfa shoots  may  start  during  the  early  days  of  March,  while  weeds 
may  grow  with  temperatures  but  little  above  freezing.  Mustard  has 
been  known  to  make  some  growth  at  32°  F. 

The  zero  point  for  the  growth  of  corn  is  49°.  This  crop  is  more 
dependent  upon  the  temperature  of  the  soil  than  upon  the  temperature 
of  the  air  above  it.  A  cold  soil  produces  slow  growth  and  late  ma- 
turity. This  fact  was  markedly  evident  in  1915  in  the  corn  crop. 
The  average  state  temperature  was  below  normal  for  the  months  that 
are  of  most  consequence  in  the  growing  period.  May  was  2.5  de- 
grees below  normal,  June  3.0  degrees,  July  3.1  degrees,  and  August 
G.I  degrees,  while  September  was  1.4  degrees  higher  than  normal. 
The  result  was  that  corn  did  not  mature  at  the  usual  time  and  much 
of  it  was  badly  injured  by  frost  even  tho  frost  did  not  occur  until 
October  6.  The  low  temperature  was  very  favorable  for  oats,  which 
require  less  heat  than  corn. 

For  the  production  of  crops  a  certain  number  of  hours  in  which 
the  temperature  is  above  the  "zero  point  of  growth"  is  necessary. 
These  are  known  as  degree-hours  and  are  ascertained  by  multiplying 
the  number  of  hours  during  which  the  temperature  is  above  the  zero 
point  of  growth  by  the  number  of  degrees  the  average  temperature  is 
above  that  point.  Assuming  that  corn  makes  no  growth  below  49°, 
and  that  it  is  planted  on  May  20  and  continues  to  grow  until  Septem- 
ber 15,  then  the  degree-hours  which  corn  has  for  its  development  in  the 
extreme  northern  district,  as  shown  by  the  temperature  records  for 
the  forty  years  from  1876  to  1915,  is  57,910.  For  comparison  with 
other  districts,  see  Table  8.

CLIMATE  OP  TLLTXOIS 


From  1876  to  1915  the  average  number  of  degree-hours  for  the 
state  for  the  growing  of  corn  was  66,708  per  year.  The  highest  num- 
ber in  any  one  season  was  75,240  in  1901,  and  the  lowest  number  was 
57,930  in  1882.  The  average  yield  of  corn  for  the  state  for  the  former 
year  was  21  bushels  and  for  the  latter  24  bushels.  During  this  forty- 
year  period,  twenty-one  years  have  been  above  normal  in  number  of 
degree-hours,  with  an  average  yield  of  30.4  bushels  of  corn  per  acre,  for 
the  state,  while  nineteen  years  have  been  below  normal,  with  an  aver- 
age yield  of  33.6  bushels ;  showing  that  better  yields  are  obtained  when 
the  temperature  is  slightly  below  normal.

30  BULLETIN  No.  208  [April, 

The  ten  years  with  the  highest  number  of  degree-hours  gave  an 
average  yield  of  29.2  bushels,  while  the  ten  years  with  the  lowest  num- 
ber gave  a  yield  of  32.3  bushels.  The  four  years  with  the  highest 
number  of  degree-hours  gave  an  average  yield  of  25.2  bushels,  while 
the  four  years  with  the  lowest  number  gave  an  average  of  30  bushels. 
The  relation  between  the  number  of  degree-hours  and  the  rainfall,  and 
the  yield  on  the  continuous  corn  plot  at  the  Experiment  Station  at 
Urbana,  is  shown  by  the  data  presented  in  Table  11.

These  data  indicate  that  altho  a  lower  yield  occurs  during  the 
years  of  higher  temperature,  the  higher  temperature  may  be  corre- 
lated with  low  rainfall,  the  consequent  lack  of  moisture  preventing 
the  crop  from  utilizing  the  temperature  possibilities. 

EXTREME  NORTHERN  DISTRICT 

The  average  temperature  for  the  six  northern  counties  that  com- 
prize the  extreme  northern  district  is  47.2  degrees.  The  average  for 
winter  is  21.8  degrees;  for  spring,  46.4  degrees;  for  summer,  70.4 
degrees,  and  for  fall,  50.3  degrees.  The  lowest  temperature  reached 
at  any  place  in  the  district  was  -31  degrees  at  Riley  in  1884,  and  the 
maximum  was  110  degrees  at  "Winnebago  in  1901,  a  range  of  141  de- 
grees. The  greatest  range  recorded  for  any  one  place  is  138  degrees 
for  Riley,  in  McIIenry  county.  The  same  range  occurred  at  Dubuquc, 
Iowa,  just  across  the  Mississippi  river,  altho  the  minimum  there 
reached  —32  degrees.  '  The  average  yearly  range  by  monthly  averages 
is  53.7  degrees. 

The  average  annual  maximum  temperature  for  this  district  is 
96.1  degrees,  and  the  average  minimum  is  -17.3  degrees,  a  range  of 
113.4  degrees.  The  average  annual  temperature  has  varied  from  43.2 
degrees  in  1885  to  49.8  degrees  in  1878,  a  range  of  6.6  degrees  (see 
Appendix,  page  121).  At  Riley,  in  McHenry  county,  twenty-four 
winters  since  1870  have  had  temperatures  of  -20  degrees  or  lower, 
while  every  winter  with  the  exception  of  1906,  1911,  and  1913  has 
reached  at  least  as  low  as  -10  degrees.  This  station  is  a  fair  represen- 
tative of  those  of  the  district.

1918]  CLIMATE  OF  ILLINOIS  33 

The  average  time  of  the  last  killing  frost  in  spring  is  May  4,  while 
the  earliest  one  in  fall  is  October  12,  thus  giving  a  growing  season  of 
161  days. 

CENTRAL-NORTHERN  DISTRICT 

The  central-northern  district  is  about  100  miles  wide  north  and 
south  and  includes  the  northern  half  of  the  corn  belt.  The  average 
temperature  for  the  forty-year  period  from  1876  to  1915  is  49.2  de- 
grees. The  average  winter  temperature  is  24.7  degrees;  of  spring, 
' 48.3  degrees;  of  summer,  71.8  degrees;  and  of  fall,  51.9  degrees.  The 
lowest  temperature  recorded  was  -30  degrees  in  February,  1905,  at 
Aledo,  in  Mercer  county,  and  at  Morrison,  in  "Whiteside  county,  while 
the  highest  was  112  degrees  at  Ottawa  in  1901.  This  gives  a  range  of 
142  degrees.  The  greatest  range  recorded  for  any  one  place  is  138 
degrees  at  Ottawa  and  at  Aledo.  The  greatest  yearly  range  by 
monthly  averages  is  52.0  degrees. 

The  average  annual  maximum  temperature  for  the  district  is 
97.4  degrees,  and  the  annual  minimum  is  -14.1  degrees.  The  lowest 
annual  temperature  was  45.7  degrees  for  1885,  while  the  highest  was 
52.1  degrees  for  1878  (see  Appendix,  page  122). 

Taking  Ottawa,  in  LaSalle  county,  as  about  the  center  of  the  dis- 
trict, it  will  be  fairly  representative  of  the  conditions  of  the  district. 
During  a  record  of  twenty-nine  years,  sixteen  summers  have  had  a 
temperature  at  some  time  of  100  degrees  or  more;  eight  winters  have 
had  a  temperature  below  -20  degrees ;  eleven,  between  -10  degrees  and 
-20  degrees;  and  nine  between  zero  and  -10  degrees.  In  1906  the 
lowest  temperature  was  3  degrees  above  zero. 

The  average  dates  for  the  latest  and  the  earliest  killing  frosts  are 
May  2  and  October  15,  giving  an  average  growing  season  of  166  days. 

CENTRAL  DISTRICT 

The  width  of  the  central  district  north  and  south  is  about  108  miles. 
The  average  temperature  is  52.4  degrees,  or  3;2  degrees  warmer  than 
the  central-northern  district.  The  average  temperature- for  winter  is 
28.8  degrees ;  for  spring,  51.9  degrees,  for  summer,  74.2  degrees ;  and 
for  fall,  54.7  degrees.  The  lowest  temperature  recorded  was  -30  de- 
grees at  LaHarpe,  in  Hancock  county,  in  1905,  and  the  highest  was 
111  degrees  at  Coatsburg,  in  Adams  county,  in  1901,  giving  a  range  of 
141  degrees.  The  greatest  range  for  any  one  place  is  140  degrees  at 
Coatsburg.  The  average  yearly  range  by  monthly  averages  is  49.6 
degrees. 

The  average  annual  maximum  temperature  for  the  district  is  98.1 
degrees,  and  the  average  minimum  is  -11.1.  The  lowest  annual  tem- 
perature was  49.6  degrees  for  1885,  and  the  highest  was  54.5  degrees

38  BULLETIN  No.  208  [April, 

for  1878  and  again  for  1913  (sec  Appendix,  page  123).  At  Springfield 
during  thirty-four  years,  sixteen  winters  have  had  temperatures  of 
-10  degrees  or  lower,  and  in  only  one  winter  was  the  lowest  tempera- 
ture above  zero.  The  lowest  temperature  recorded  was  -24  degrees 
in  1905.  The  coldest  day  of  the  year  occurred  in  January  during 
seventeen  years,  in  February  during  twelve  years,  and  in  December 
five  years.1  The  maximum  summer  temperature  varies  from  91  de- 
grees to  107  degrees.  Eight  summers  since  1880  have  reached  a  tem- 
perature of  100  degrees  or  higher. 

The  average  dates  for  the  latest  and  the  earliest  killing  frosts  in 
spring  and  fall  are  April  26  and  October  16,  giving  an  average  grow- 
ing season  of  173  days. 

CENTRAL-SOUTHERN  DISTRICT 

The  approximate  average  width  of  the  central-southern  district 
north  and  south  is  105  miles. '  The  average  temperature  is  55.3  de- 
grees, or  2.9  degrees  warmer  than  the  central  district.  The  average 
temperature  for  winter  is  33.1  degrees,  for  spring,  55.0  degrees;  for 
summer,  76.1  degrees ;  and  for  fall,  57.2  degrees.  The  lowest  temper- 
ature recorded  was  -29  degrees  at  Montrose,2  in  Effingham  county,  in 
1915,  while  the  highest  was  113  degrees  at  Greenville,  in  Bond  county, 
in  1901,  giving  a  range  of  142  degrees.  The  greatest  range  for  any 
one  place  is  134  degrees  at  Greenville,  "f  he  greatest  yearly  range  by 
monthly  averages  is  46.7  degrees. 

The  average  annual  maximum  temperature  for  this  district  is 
99.8  degrees,  and  the  average  minimum  is  —7.1  degrees,  a  range  of 
106.9  degrees.  The  lowest  annual  temperature  was  52.9  degrees  for 
1885,  while  the  highest  was  57.6  degrees  for  1908,  giving  a  range  of 
4.7  degrees  (see  Appendix,  page  124). 

At  McLeansboro,  during  twenty-six  years,  sixteen  summers  have 
reached  a  temperature  of  100  degrees  or  above,  the  highest  being  110 
degrees.  The  lowest  winter  temperatures  were  -10  degrees  or  lower 
during  ten  winters,  between  zero  and  -]  0  degrees  during  nine  winters, 
and  above  zero  during  seven  winters.  The  lowest  temperature  was 
-19  degrees,  and  the  range  for  the  district  129  degrees. 

The  average  dates  of  killing  frosts  in  spring  and  fall  are  April  15 
and  October  20,  giving  an  average  growing  season  of  188  days. 

EXTREME  SOUTHERN  DISTRICT 

The  extreme  southern  district  includes  the  seven  southern  coun- 
ties and  is  approximately  42  miles  from  north  to  south.  The  Ozark 
"Ridge  extends  east  and  west  across  the  northern  part  of  the  district. 
The  highest  point  in  southern  Illinois,  1,046  feet  above  sea  level  in 
the  northwest  part  of  Pope  county,  is  on  this  ridge. 


'In  this  respect,  Springfield  is  fairly  representative  of  the  state  as  a  whole. 
sRecords  at  Montrose  have  heen  kept  only  for  the  years  1912-191.').

42  BULLETIN  No.  208  [ April, 

The  average  temperature  for  the  district  is  57.9  degrees,  which  is 
10.7  degrees  higher  than  the  average  for  the  extreme  northern  dis- 
trict. The  average  temperature  for  the  winter  months  is  37  degrees ; 
for  spring,  57.8  degrees;  for  summer,  77.4  degrees;  and  for  fall,  59.6 
degrees.  These  temperatures  are  higher  than  those  of  the  extreme 
northern  district  by  15.2  degrees  in  winter,  11.4  degrees  in  spring,  7.0 
degrees  in  summer,  and  9.3  degrees  in  the  fall.  The  lowest  recorded 
temperature  was  -26  degrees  at  New  Burnside,  in  Johnson  county, 
in  1912,  while  the  highest  was  106  degrees  at  Cairo  in  1901,  a  range 
of  132  degrees.  The  greatest  recorded  range  in  any  one  place  is  130 
degrees  at  New  Burnside.  The  greatest  yearly  range  by  monthly 
averages  is  43.7  degrees. 

The  average  annual  maximum  temperature  for  the  district  is  99.0 
degrees,  and  the  minimum  -5.2  degrees,  a  range  of  104.2  degrees. 
The  lowest  annual  temperature  was  55.4  degrees  for  1886,  and  the  high- 
est was  59.8  degrees  for  1900  (see  Appendix,  page  125). 

The  average  dates  for  the  latest  and  the  earliest  killing  frosts  in 
spring  and  fall  are  April  14  and  October  24,  thus  giving  a  growing 
season  of  193  days.  This  is  thirty-two  days  longer  than  the  growing 
season  of  the  extreme  northern  district. 

The  average  daily  maximum  temperature  is  18  degrees  higher  in 
the  extreme  southern  than  in  the  extreme  northern  district,  for  Jan- 
uary and  February,  but  only  2  degrees  higher  for  July  and  4  degrees 
for  August. 

TEMPERATURE  OF  SOIL 

The  temperature  of  the  soil  is  a  very  important  factor,  not  only 
in  plant  growth  as  usually  manifest,  but  also  in  the  biological  activ- 
ities taking  place  in  the  soil,  by  which  nitrification  proceeds.  It  is 
dependent  upon:  (1)  the  moisture  content  of  the  soil,  (2)  the  color, 
(3)  the  compactness,  (4)  the  vegetative  covering,  and  (5)  the  incli- 
nation of  the  surface  of  the  soil  to  the  sun's  rays.  It  is  not  necessary 
to  discuss  each  of  these  factors  separately,  and  further,  it  would  be 
difficult  to  say  which  is  of  the  greatest  importance.  Under  varying 
conditions  each  may  in  turn  be  the  factor  of  greatest  influence. 

The  average  monthly  temperature  of  the  soil  to  a  depth  of  1  to 
3  inches  is  always  higher  than  that  of  the  air  above  it. 

Table  24  shows  the  annual  maximum  and  minimum  temperatures 
of  soil  at  various  depths  as  recorded  for  sixteen  years  at  this  station. 
It  will  be  noted  that  in  only  three  winters  out  of  the  sixteen  re- 
corded did  the  temperature  of  the  soil  at  a  depth  of  12  inches  fail  to 
reach  as  low  as  32  degrees,  or  the  freezing  point.  From  this  fact  it  is 
evident  that  during  most  winters  the  soil  freezes  deeper  than  12  inches.

BULLETIN  No.  208 


[April, 


The  lowest  temperature  for  the  12-inch  depth  was  23  degrees  in  1905. 
The  24-inch  thermometer  was  not  used  until  1912,  but  since  that  time 
the  lowest  temperature  recorded  at  that  depth  was  35.5  degrees ;  which 
fact  would  indicate  that  frost  reaches  but  little  beyond  the  12-inch 
depth.  The  winter  having  the  deepest  frost  penetration  was  in  1905, 
when  the  lowest  temperature  recorded  by  the  36-inch  thermometer  was 
35  degrees,  and  of  the  12-inch  thermometer  23  degrees.  (In  Febru- 
ary, 1917,  the  24-inch  thermometer  reached  32  degrees,  and  the  12- 
inch  24.5  degrees.  The  soil,  therefore,  must  have  frozen  to  a  depth 
of  24  inches  at  least,  from  which  it  is  evident  that  in  1905  the  frost 
must  have  penetrated  to  an  even  greater  depth.) 

Table  25  gives  the  temperature  of  soil  at  different  depths  by 
monthly  averages.

The  times  of  killing  frosts  in  spring  and  autumn  are  very  impor- 
tant, as  they  determine  the  length  of  the  growing  season.  From  data 
collected  it  has  been  found  that  the  average  date  of  the  last  killing 
frost  in  spring  and  the  first  in  autumn,  for  each  district  in  the  state, 
is  as  recorded  in  Table  26. 

The  growing  season  is  nearly  two  weeks  longer  in  the  central  than 
in  the  extreme  northern  district,  while  in  the  extreme  southern  dis- 
trict it  is  nearly  three  weeks  longer  than  in  the  central.  The  average 
length  of  the  growing  season  for  the  northern  tier  of  counties  is  161

days,  while  that  of  the  seven  southern  counties  is  193  days,  or  nearly 
five  weeks  longer.  Observations  in  cities  of  some  size  show  that  the 
last  killing  frost  in  spring  is  earlier  and  the  first  in  fall  later  than 
in  country  districts.

The  latest  killing  frosts  in  spring  recorded  for  northern  Illinois 
were  on  June  9,  1901,  in  Winnebago  and  Carroll  counties;  on  May  27, 
1915,  at  Dakota  in  Stephenson  county;  and  on  May  31,  1897,  over  this 
district  generally.  The  earliest  killing  frosts  in  fall  were  reported 
at  Dakota,  August  30,  1915,  and  at  Lanark,  September  12,  1902.  The 
earliest  general  killing  frost  for  this  section  was  on  September  18, 
1901. 

In  central  Illinois  the  latest  killing  frost  in  spring  was  recorded 
at  Philo,  Champaign  county,  on  May  31,  1897,  while  Springfield  re- 
corded one  on  May  29, 1882.  A  somewhat  general  killing  frost  occurred 
on  May  24,  1892.  The  earliest  killing  frost  in  fall  for  this  section  was 
recorded  at  Springfield  on  September  13,  1890,  and  one  of  rather  gen- 
eral occurrence  was  recorded  on  September  18,  1901. 

For  southern  Illinois  the  latest  killing  frost  in  the  spring  was  on 
May  31,  1894,  while  the  latest  general  one  at  this  season  was  on  May 
14,  1895.  The  earliest  in  fall  was  on  September  14,  in  1902,  while  a 
general  one  occurred  on  September  30, 1899,

WIND 


Illinois  lies  in  the  belt  of  the  prevailing  westerly  winds,  in  which 
the  general  atmospheric  movement  is  from  west  to  east;  yet  the 
presence  of  the  cyclones  and  anticyclones  causes  great  variation  both 
in  direction  and  in  velocity. 

DIRECTION 

In  Table  27  is  shown  the  wind  direction  as  determined  for  sea- 
sons rather  than  for  months.  The  effect  of  Lake  Michigan  in  modify- 
ing the  direction  of  the  wind  places  a  small  area  of  northeastern  Illi- 
nois in  a  region  by  itself,  which  may  be  designated  as  the  lake-breeze 
area.  In  this  section  the  wind  blows  from  the  northeast  during  40.8 
percent  of  the  time  in  the  spring  and  37.5  percent  of  the  time  in  the 
summer  months,  while  during  the  fall  and  winter  months  it  blows 
from  the  west  and  the  south.

VELOCITY  OF  AIR  MOVEMENT 

The  data  regarding  wind  velocity  have  been  obtained  from  the 
published  records  of  the  stations  of  the  Weather  Bureau  within  the 
state  and  the  five  along  the  Mississippi  river.  The  anemometer,  the 
regular  Weather  Bureau  instrument,  is  used  for  determining  the  ve- 
locity of  the  air  movement,  but  comparisons  of  the  data  of  the  various 
stations  are  very  unsatisfactory  because  of  the  varying  heights  of  the 
instruments  above  the  ground  or  above  the  buildings  surrounding 
them.  They  vary  in  height  from  70  feet  to  over  200  feet  above  the 
ground. 

The  velocity  of  the  wind  is  greatest  during  November,  December, 
January,  February,  March,  and  April,  when  the  average  hourly  ve- 
locity is  10.4  miles;  while  May,  June,  July,  August,  September,  and 
October  have  the  least  atmospheric  movement,  8.0  miles  per  hour. 
March  and  April  are  the  windiest  months,  while  July  and  August 
have  the  least  wind  movement.  The  season  of  greatest  wind  velocity 
is  very  significant  to  the  farmer  because  of  the  resulting  increased 
evaporation.  Table  28  gives  the  velocity  for  the  three  divisions  of  the 
state.

At  the  surface  of  the  earth  the  air  movement  is  much  less  than 
at  a  height  of  even  a  few  feet,  yet  it  is  sufficient  to  play  a  very  impor- 
tant part  in  increasing  the  amount  of  evaporation  from  the  surface 
soil.  Experiments  have  shown  that  when  the  air  movement  is  5  ' 
miles  per  hour,  the  amount  of  evaporation  is  increased  2.2  times 
over  what  it  is  during  a  calm;  when  10  miles  per  hour,  3.8  times; 
when  15  miles,  4.9  times ;  when  20  miles,  5.7  times ;  when  25  miles, 
6.1  times ;  and  30  miles  per  hour  increases  the  evaporation  6.3  times. 
The  effect  of  a  windbreak  on  evaporation  has  been  shown  by  an  experi- 
ment in  which  it  was  determined  that  at  150  feet  from  a  hedge  the 
evaporation  was  21.3  percent  greater  than  at  20  feet,  and  at  300  feet, 
30  percent  greater. 

The  effect  of  a  crop  in  preventing  evaporation  from  the  surface 
of  the  soil,  thru  the  holding  of  a  stratum  of  air  possessing  little  move- 
ment and  consequently  becoming  highly  charged  with  moisture,  is 
very  striking,  Hay  and  small  grain  crops  are  especially  influential 


SO  BULLETIN  No.  208  \April, 

in  this  respect.  In  oat  fields  of  heavy  growth,  the  dew  on  the  lower 
parts  of  the  plants  will  not  evaporate  sometimes  until  nine  or  ten 
o'clock  in  the  morning,  and  it  begins  to  be  deposited  at  four  or  five 
o'clock  in  the  afternoon.  On  June  29,  1910,  the  relative  humidity  in 
a  field  of  oats  two  inches  above  the  soil  and  at  the  same  height  in  the 
open,  was  determined  during  the  day.  The  mean  relative  humidity 
in  the  oats  was  80.4  percent,  while  in  the  open  it  was  53.4  percent, 
or  a  difference  of  27  percent.  This  difference  was  due  to  shading 
and  to  lack  of  air  movement  in  the  oats.  At  six  inches  above  the  oats, 
the  relative  humidity  was  58.6,  and  the  average  wind  velocity  was  3.2 
miles  per  hour,  while  in  the  oats  no  movement  occurred.  It  has  been 
determined  that  for  low  wind  velocity  the  increased  evaporation  rate 
due  to  wind  is  .5  percent  per  day  for  each  mile  of  wind. 

Air  movement  not  only  increases  the  evaporation  from  the  soil, 
but  also  the  amount  of  transpiration,  or  exhalation,  of  water  from  the 
leaves  of  the  plant,

SUNSHINE  AND  CLOUDINESS 


51 


The  amount  of  sunshine  needed  in  the  growth  of  crops  varies 
somewhat  with  the  crop,  but  all  our  principal  cereals  require  sunshine 
during  a  large  part  of  the  time.  Rather  strong  light  is  needed  for  the 
formation  of  starch. 

December,  January,  February,  March,  and  April  are  the  cloudy 
months  of  the  year,  having  sunshine  for  only  45.6  percent  of  the  time 
possible,  while  the  other  months  have  sunshine  for  56.4  percent  of  the 
time.  August  has  the  greatest  amount  of  sunshine,  60.6  percent, 
while  December  has  least,  42.3  percent.  The  extreme  southern  part 
of  the  state  has  the  least  amount  of  sunshine  for  the  year,  47.7  per- 
cent. December  and  January  in  this  district  have  only  39.3  percent.

Sunshine  increases,  not  only  the  amount  of  evaporation  from  the 
soil,  but  also  largely  the  loss  of  moisture  from  the  leaves  of  plants  by 
transpiration.  When  the  soil  is  shaded,  the  loss  of  water  by  evapora- 
tion is  checked.  A  soil  shaded  by  dry  rye  plants  evaporated  13.9 
percent  less  than  the  same  soil  not  so  shaded. 


RELATIVE  HUMIDITY 

The  relative  humidity  is  the  percentage  of  moisture  actually  pres- 
ent in  the  air  as  compared  with  the  amount  which  the  air  is  capable 
of  holding  in  vapor  form.  The  relative  humidity  is  lowered  by  a  rise 
of  temperature  and  increased  by  a  lowering  of  temperature.  A  lower- 
ing of  temperature  causes  deposition  of  dew.  On  the  other  hand,  when 
clouds  prevent  the  necessary  lowering  of  temperature  there  is  no  dew. 

At  the  Illinois  Experiment  Station  the  mean  humidity  for  Novem- 
ber, December,  January,  February,  and  March  is  83.5  percent,  while 
for  the  other  months  it  is  74.2  percent,  or  9.3  percent  less.1  The  year 
1911  had  the  lowest  relative  humidity  of  any  year  during  which  the 
humidity  record-  has  been  kept  at  the  University  of  Illinois.  The  mean 
humidity  for  May,  June,  July,  and  August  of  that  year  was  56  per- 
cent, and  for  the  entire  year  67.8  percent.
